Super-agers are individuals known to maintain peak mental prowess well into their 90s and avoid dementia and Alzheimer's disease. While genetics play a big part in super-agers' cognitive health, adopting healthy lifestyle habits also contributes, and other people might be able to improve their brain health in the same way. These habits include exercising regularly, following a plant-based diet, being social, adopting mentally challenging activities, and getting adequate sleep.

A 2024 study suggests that exposure to high temperatures may increase the risk of an ischemic stroke. High temperatures may trigger dehydration, which can make the blood more viscous and more likely to clot.

A 2024 nationwide poll suggests that one in four older adults takes aspirin regularly in hopes of preventing a heart attack or stroke, even though updated guidelines from 2019 advise against that practice in many cases.

Migraines and cardiovascular disease share certain common features, including changes in blood vessels, blood flow, and inflammation. Migraine with aura is linked to an increased risk of stroke, and common migraine drugs called triptans are linked to a higher risk of stroke and heart attack in people at risk for cardiovascular disease. Although both of these risks are extremely small, migraine sufferers with heart-related risks should seek out a personalized approach for treatment and know the warning signs of a stroke.

A 2023 study suggests a blood test that looks for a specific biomarker may help identify people with Alzheimer's disease who may benefit from anti-amyloid therapy long before the disease is evident.

A 2024 study suggests that women with polycystic ovary syndrome, a condition stemming from a hormonal imbalance, may face higher risks of cognitive decline at midlife.

A 2024 study suggests that younger women with migraines and early menopause symptoms such as hot flashes and night sweats may have higher cardiovascular risks at midlife.

There is no cure for Alzheimer's, but medication can help manage the disease. Currently, the main FDA-approved drugs used to treat Alzheimer's are symptomatic drugs, which ease symptoms but don't address the cause of the disease. A new medication has been shown to slow the disease's progression and reverse some of its effects on memory among people with mild Alzheimer's.

Studies on alcohol's health effects have shown conflicting results, Harvard experts say, leaving people confused. No randomized, controlled trials have been performed, and observational studies can't easily tease apart drinking and other lifestyle habits that influence health, such as exercise, sleep, and social connectedness. However, drinking alcohol has been convincingly linked to developing breast cancer, so women concerned about their breast cancer risk should consider reducing or eliminating alcohol. For most other healthy people who enjoy an occasional drink, they can continue to do so.

In a 2024 study, men diagnosed with erectile dysfunction who took popular PDE5 inhibitors to treat their condition had a lower risk of developing Alzheimer's than men who didn't use medication.
